Transmission Mode Switch: Description and Operation

42LE - Automatic Transmission
AUTOSTICK SWITCH

DESCRIPTION
Autostick is a driver-interactive transmission feature that offers manual gear shifting capability to provide you with more control. Autostick allows you to maximize engine braking, eliminate undesirable upshifts and downshifts, and improve overall vehicle performance. This system can also provide you with more control during passing, city driving, cold slippery conditions, mountain driving, trailer towing, and many other situations.

OPERATION
Autostick is a driver-interactive transaxle feature that offers manual gear shifting capability. When the shifter is moved into the Autostick position, the transaxle remains in whatever gear it was using before Autostick was activated. Moving the shifter to the left (towards the driver) causes a downshift and moving to the right (towards the passenger) causes an upshift. The instrument cluster will illuminate the selected gear. The vehicle can be launched in 1st, 2nd, or 3rd gear while in the Autostick mode. The speed control is operable in 3rd and 4th gear Auto stick mode. Speed control will be deactivated if the transaxle is shifted to 2nd gear. Shifting into OD position cancels the Autostick mode, and the transaxle resumes the OD shift schedule.

DEACTIVATION
The autostick feature will be deactivated if one of the following conditions occur:
- DTC P0706-Check Shifter Signal-usually accompanied by all PRNDL lights turning on in Park and Neutral. This will result in a DTC P0706 if three such errors are detected after any one "key-on".
- DTC P0951-Autostick Input Circuit
- DTC P1797-Manual Shift Overheat- (Transmission oil temperature >275°F) or (Engine coolant temperature >255°F).

Acceptable powertrain temperature must be achieved to reactivate Autostick after a high temperature fault:
- Transmission Oil Temperature <255°F
- Engine Coolant Temperature <240°F

AUTOMATIC OVERRIDES
For safety, durability, and driveability, some shifts are executed automatically or prevented.
